摘要:

研究分析不同浓度的柠檬酸溶液在不同的液料比和不同作用时间下花生中B族黄曲霉毒素的含量变化。结果表明,随着柠檬酸溶液浓度的提高,液料比的增加,作用时间的延长,花生中B 族黄曲霉毒素的含量降低,脱毒效果越好。用80g/L 的柠檬酸溶液,液料比(V/m)为5:1 对霉变后染有B 族黄曲霉毒素(AFB1 和AFB2)的花生颗粒(98.60μg/kg)浸泡30min 具有很好的脱毒效果,处理后,黄曲霉毒素含量小于20μg/kg,达到国标GB2761 — 2005 对花生中黄曲霉毒素限量的要求。

Abstract:

Citric acid treatment was applied to decontamination of B-aflatoxins in naturally mouldy peanuts, because this treatment is mild and safe without residual toxicity. Effects of citric acid concentration, liquid/solid ratio and treatment duration on content of B-aflatoxins in the peanuts were investigated. Results showed that increased citric acid concentration and liquid/ solid ratio and extended treatment duration resulted in decease of content of B-aflatoxins in the peanuts. After the treatment for 30 min with 80 g/L citric acid solution at the liquid/solid ratio of 5:1 (ml/g), the content of B-aflatoxins decreased from 98.60μg/kg to below 20 μg/kg, which is the limit stipulated in Chinese national standard (GB2761—2005).

Key words: decontamination, B-aflatoxins, citric acid, peanut
